Adults inhabit shallow coastal waters with rocky substrate. They are found under overhanging rocks, entrances of caves and other biotopes with reduced light. In the Atlantic, they occur in shallow, light-exposed biotopes. They feed on benthic invertebrates, also on harpacticoids (Ref. 4785), amphipods and other copepods (Ref. 94105). Males court by figure-8-swimming (Ref. 4785). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
